The triarchic model posits that distinct trait constructs of boldness, meanness, and disinhibition underlie psychopathy. The triarchic model traits are conceptualized as biobehavioral dimensions that can be assessed using different sets of indicators from alternative measurement modalities; as such, the triarchic model would hypothesize that these traits are not confined to any one item set. The present study tested whether the triarchic model dimensions would emerge from a hierarchical-structural analysis of the facet scales of the Elemental Psychopathy Assessment (EPA), an inventory designed to comprehensively index psychopathy according to the five-factor personality model.

Attention-deficit/hyperactivity disorder (ADHD) symptoms are associated with myriad adverse outcomes, including interpersonal difficulties, but factors that moderate the developmental course and functional impact of ADHD over time are not well understood. The present study evaluated developmental contributions of the triarchic neurobehavioral traits (boldness, meanness, and disinhibition) to ADHD symptomatology and its subdimensions from adolescence to young adulthood. Participants were twins and triplets assessed at ages 14, 17, and 19 (initial = 1,185, 51.

The triarchic model of psychopathy posits that three distinct trait dispositions-disinhibition, meanness, and boldness-contribute to the interpersonal, affective, and impulsive-unrestrained features of this condition and is represented to varying degrees in all conceptualizations and measures of psychopathy. Using data for incarcerated males ( = 273) and females ( = 83) from 10 different prisons in Italy, we specified a latent variable model of the triarchic trait constructs in which scale measures of disinhibition, meanness, and boldness composed of items from the following inventories served as indicators: Triarchic Psychopathy Measure, Psychopathic Personality Inventory-Revised, Minnesota Multiphasic Personality Inventory-2 Restructured Form, and NEO Five Factor Inventory. A correlated three-factor solution evidenced adequate model fit, with individual triarchic trait scales loading strongly onto their target factors.

Trait anger has been shown to be predictive of emotion-focused coping and alcohol use. Yet, the connection between cannabis use and trait anger remains poorly characterized. The present study sought to investigate the relationship between cannabis use and self-reported trait anger in youth seeking substance use treatment.

The validity of self-report psychopathy assessment has been questioned, especially in forensic settings where clinical evaluations influence critical decision-making (e.g., institutional placement, parole eligibility).

Background: It is critical to promptly identify and monitor mood and anxiety symptoms in young people with SUD. The primary aim of this study was to conduct a psychometric validation of the Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder scale (GAD-7) for depression and anxiety screening in young people seeking outpatient treatment for SUD. Our secondary aim was to compare the performance of the PHQ-9 and GAD-7 to their briefer two-item versions (PHQ-2 and GAD-2) in terms of detecting probable mood and anxiety disorders.

Youth experiencing psychosis also frequently misuse substances, making it clinically challenging to differentiate substance-induced psychosis (SIP) from a primary psychotic disorder (PPD), which has important implications for management and prognosis. This article presents practical considerations related to differentiating SIP from PPD, including information on substances associated with symptoms of psychosis. Recommendations for management of SIP are also reviewed, including screening for and treating comorbid substance use disorders and using evidence-based medication and psychosocial interventions.
